On Wednesday, Colorado Parks and Wildlife released the latest map showing collared wolf activity over the last month.

The map, published on the fourth Wednesday of each month, does not show actual locations where the wolves have been, instead depicting watersheds where at least one GPS point of wolf activity has been detected.

Between March 26 and April 23, wolf movement has been confirmed in watersheds east of the Continental Divide and into the Front Range. Wolf activity continues to be detected in the Eagle River Valley watershed.

Between Dec. 18 and 22, Colorado Parks and Wildlife released 10 gray wolves onto public land in Summit and Grand counties. In addition to those 10 wolves, two male wolves captured in the North Park area of Colorado in February 2023 were fitted with collars and are part of the map data.

While all 12 wolves had working collars as of February’s map report, there are now only nine wolves with working collars. One of the collars stopped working in March, and a second collar that was partially functioning in March has since failed.

“The animals with the failed collars are traveling with other animals with functional collars, which currently allows CPW to monitor those animals,” Colorado Parks and Wildlife said in the report. “CPW has confirmed that the animals with the malfunctioning collars are still alive based on visual confirmation from an airplane.”

Last week, one of the 10 wolves reintroduced in December was found dead in Larimer County. While initial evidence suggests that the wolf died of natural causes, the U.S. Fish and Wildlife Service has sent the carcass for a necropsy to produce a final determination of the cause of death.

Since the last report in late March, wolves have been blamed for the deaths of six cows in Grand and Jackson counties. Currently, ranchers are entitled to compensation from Colorado Parks and Wildlife for the market value of cattle lost to wolves, and can take dedicated nonlethal measures to protect livestock against wolf attacks.

Alongside the wolf activity report, Colorado Parks and Wildlife launched a Gray Wolf Depredation Report webpage, where information can be found on the dates, locations and results of confirmed wolf-related livestock losses.
